Abstract

The utility model relates to a zipper tape structure for a cold insulation bag, in particular to a structure of a zipper tape of a cold insulation bag. The structure comprises a zipper tape used for connecting at the opening of the cold insulation bag; and one end of the zipper tape is connected with zipper teeth. The structure is characterized in that the zipper tape is compounded by a polyolefin film and non-woven fabric. The structure mainly solves the technical problems that the conventional cold insulation bag has poor sealing and heat preservation effects and the heat seal of the bag body is difficult; and the structure can ensure that the cold insulation bag has stronger heat preservation effect, and is waterproof and airtight so as to prolong the cold insulation or heat preservation time.

Description

A kind of zipper cloth based structures of cold-keeping bag

Technical field

The utility model relates to the zipper cloth based structures of slide fastener fabricbase, particularly a kind of cold-keeping bag.

Background technology

At present, people generally are to use common shopping bag when buying frozen foods, and its function only limits to loading and packing, can not be incubated, in use can very fast fusing at frozen food.In view of the foregoing, the dealer has invented the sack with heat insulation function.As Chinese utility model patent specification sheets (Granted publication number: CN2300613Y) disclose a kind of cold insulation or thermal protective aid.It comprises: main bag, it is made of at least two layer materials, be external structure layer and the adiabatic layer in it, also comprise inside liner, main bag comprises bottom, wall on every side and top cover, and is provided with the switching mouth, also has the outer bag that fuses with main bag in the outside of main bag, diapire and wall all around should outer bag be arranged, and described outer bag inwall and container shapes are adaptive, and removable adjusting position, shape and container adaptive vertical dividing plate or spacer block are arranged.The external structure layer of making described thermal protective aid bag can use any suitable bagging, for example: cloth, thick cloth, canvas, synthetic fiber cloth; Adiabatic layer can use any soft thermal insulating material, and for example: the cotton-shaped material that cotton, hair, syntheticfibres or its compound are made also can be foamed plastic or other porous materials; Described inside liner can be any flaky material, for example: plastic film or synthetic film.It can play actv. cold insulation (insulation) effect.But said structure has following shortcoming:

1, is not equipped with the zipper cloth based structures that plays fine insulation, sealing effectiveness and antiseep for cold insulation (insulation) bag.

2, because the material selection cause of bag, the oxygen permeability height of bag, leak tightness are poor, cause cold insulation (insulation) effect not ideal enough.

3, owing to the material selection cause of bag, the insufficient strength of bag, durability are not good, and the situation of infiltration takes place easily.

In addition, Chinese utility model patent specification sheets (Granted publication number: CN2907326) disclose a kind of slide fastener handbag.It is provided with a belt body with length, the dual-side of this belt body is respectively equipped with zipper teeth, a belt body wherein end is provided with the bottom, bottom center is provided with zipper teeth, central authorities' zipper teeth and the belt body wherein zipper teeth of a side pass through the slider of zipper fastener interlock, the belt body other end is two belts by centre slit, and two belts have suitable spacing, and the end that belt body is positioned at belt is provided with a ring body; Slider of zipper fastener is along the zipper teeth drawing gradually in regular turn of belt body dual-side, and makes belt body around connection, constitutes handbag; The opening edge of this slide fastener handbag is provided with for the belt that hand lifts or shoulder is born, and cost is low, is convenient to collection.But the slide fastener belt body of this slide fastener only is to adopt the cloth of common looped fabric to make, and common looped fabric cloth material has certain permeability to air and water permeability, therefore, just is unfavorable for cold insulation (insulation) on the cold-keeping bag as if this structure is transplanted to.

The utility model content

The purpose of this utility model is to provide a kind of zipper cloth based structures of cold-keeping bag, mainly solve existing cold-keeping bag lack play better seal and heat insulation effect and with the technical matters of the slide fastener fabricbase of polyolefin bag heat seal, it not only makes cold-keeping bag reach stronger heat insulation effect, and do not seep water, airtight, prolonged cold insulation or temperature retention time.

For achieving the above object, the utility model is achieved in that

A kind of zipper cloth based structures of cold-keeping bag, it comprises the zipper teeth that is used to be connected the cold-keeping bag sack, and this fabricbase one end connects zipper teeth, and it is characterized in that: described belt body polyolefin layer nonwoven layer is composited.

By said structure, advantage of the present utility model is:

Zipper cloth based structures of the present utility model cooperates insulation complex pocket body structure can reach stronger heat insulation effect, and guarantee a slide fastener fabricbase and a bag connecting bridge do not seep water, airtight, help to prolong cold insulation or temperature retention time.

Description of drawings

Fig. 1 is the structural representation of slide fastener fabricbase of the present utility model;

Fig. 2 is the structural representation of cold-keeping bag that the structure of the utility model slide fastener fabricbase is installed;

Fig. 3 is the lamination layer structure scheme drawing of the utility model bag.

The specific embodiment

See also Fig. 1, the utility model discloses a kind of zipper cloth based structures of cold-keeping bag.As shown in the figure: it comprises the slide fastener fabricbase 41 that is used to be connected cold-keeping bag 1 sack, and these fabricbase 41 1 ends connect zipper teeth 42, it is characterized in that: described fabricbase 41 is to be composited by polyolefin layer 411 and nonwoven layer 412.

Shown in Fig. 2,3, above-mentioned slide fastener fabricbase is mounted on 1 mouthful of cold-keeping bag by the mode of heat seal.And described cold-keeping bag bag ecto-entad is by vacuum plated aluminum film 101, polyolefin film successively, and heat-insulation layer, polyolefin complex film are made up of combination process.This zipper cloth basigamy closes insulation complex pocket body structure can reach stronger heat insulation effect, and guarantee the zippered bag part do not seep water, airtight, help to prolong cold insulation or temperature retention time.

Claims

1. the zipper cloth based structures of a cold-keeping bag, it comprises the slide fastener fabricbase (41) that is used to be connected cold-keeping bag (1) sack, these fabricbase (41) one ends connect zipper teeth (42), it is characterized in that: described fabricbase (41) is to be composited by polyolefin layer (411) and nonwoven layer (412).
